Profoto PRO-10 2400 Ws Air TTL Generator To say the Profoto Pro-10 is fast is an understatement, with a breathtaking flash duration of up to 1/80, 000 of a second. But what really sets the Pro-10 apart is that it’s the perfect fusion of speed & power – 2400 Ws of power to be exact. The light output it generates is truly enormous & it provides a shorter flash duration than any other flash across the entire power range. This dramatically increases the scale of what you can shoot & freeze, everything from a water splash to a waterfall are perfectly frozen in time. Recycling time is equally impressive. The Pro-10 can easily match the fastest cameras even when the light output is set high, making it easier to capture the perfect moment by shooting in bursts. Combine all of that with TTL & Profoto’s patented High Speed Sync (HSS) technology, & you have a flash that is capable of handling any & all lighting challenges. Ultimately the Profoto Pro-10 is so much more than the world’s fastest studio flash – it’s your imagination set free. It’s the speed to exceed.
